usb host读写U盘！

采用UART方式0与LM74通信。 用C8051f020的P0.7作片选，主机通过TXD发送时钟信号，实现同步通信,半双工.RXD 作双向数据线.用六位数码管显示LM74采集的温度值-The use of UART communication mode 0 and LM74. P0.7 used for the C8051F020 chip select, host TXD sent through the clock signal, to achieve synchronous communication, half-duplex. RXD for bi-directional data line. With six digital tube display LM74 temperature collected

温度传感器18B20的典型应用，通过18B20采集温度，可以精确到小数点两位，在LED或LCD上显示-Temperature Sensors Typical applications 18B20, 18B20 collected through the temperature, can be accurate to two decimal places, in the LED or LCD display

这是一个AVR开发板的所有必需的源码，包括原理图，PCb图以及调试用的C例程-This is an AVR development board of all the necessary source code, including schematics, PCb map and debug using the C routines

用51单片机驱动汽缸动作,很方便使用 广泛用于测试领域-MCU-driven cylinder with 51 movements, it is easy to use the area extensively for testing

这是相关T6963c(240*128)液晶驱动（AVR Mega128) C语言 ,这是转载的程序-T6963c (240* 128) LCD driver (AVR Mega128) C language, which is reproduced in the process

本文件介绍了MSC51与AVR单片机的区别，同时，对它们的区别的使用代码进行了说明-This document presents the AVR microcontroller with MSC51 distinction, at the same time, the difference between their use of the code described

采用PDIUSBD12开发的USB总线与429总线数据转换的单片机固件程序-used PDIUSBD12 development of the USB bus with 429 data conversion MCU firmware
